SPECIFICATION forming part of Letters Patent No. 234,877, dated November 30, 1880.

Application filed April G, 1880.

To all whom t may concern:

Be it known that I, JOHN LA DOW, of the city and county of Albany, and State of New York, have invented a new and useful Chase for Printers, of which the following is a specification.

My invention relates to improvements in printers chases, as will hereinafter be more fully set forth, and illustrated in the accompanying drawings.

Figure l is a perspective view of the chase and locking-up device with type or matter locked centrally in the chase. Fig. 2 is a crosssectional view taken at line No.1 in Fig. 1. Fig. 3 is a sectional view taken at line No. 2 in Fig. l. Fig. et is a face View of the chase and locking-up device with type or matter locked up at one corner of the chase. Fig. 5 is a face view of the chase and lockingup device with type or matter diagonally locked in place, and Fig. 6 is a face view of the chase and locking devices with several pages of matterlooked in place.

In the drawings similar letters refer to similar parts throughout the several views.

The chase proper consists of a cast or wrought iron frame of rectangular form, with sides A A A A', as shown, and substantiallyr as heretofore employed. The sides A A of the chase are perforated in their end portions with one or more holes, a a, running horizontally through said sides, which perforations receive removable rods or bars B B, that nicely fit therein. The said bars are preferably made of steel, and are intended to hold the locking device within the chase and readily permit pages to be removed or inserted, as may be required, as I will hereinafter fully describe.

Supported within the chase A A by the bars B B are two or more pairs of bars, C, forming what I denominate duplex lockingbars.7 These duplex locking-bars consist each ofa pair of flat steel bars made of a length equal to the length of the chase, inside measure, and are perforated at' short intervals to form piu-holes c c, as shown in Fig. 3. At the ends of each pair of duplex bars are employed clamping screws s s, which screws loosely pass through the upper or face bar of the pair and workin to screw-threaded holes madein the (Model.)

lower side bar, and when tightened cause the f,

ends of the duplex bars to clamp the bars B B, as shown in Figs. 1 and 3.

Arranged transversely with the duplex locking-bars C C, and within the space d,.forrned between the upper and lower bars of said duplex looking-bars, are two or more cross locking-bars, D D, each formed by a single piece of .steel and provided with pin-holes c c, arranged at intervals apart, as shown in the several gures. These cross locking-hars are made uniformly with a length equal to the width of the chase, inside measure., so that their ends will touch the inner side surface of the side portions, A A, of the frame, as shown in Fig. 2.

Pins m m, made preferably of steel and adapted to he inserted in any of the pin-holes c c of the duplex locking-bars, are employed to hold one of the cross. locking-bars up to the head or foot end of the page or pages to be locked up. Similar pins, m m', also inserted in said duplex locking-hars, are employed to hold a similar cross locking-bar against the opposite end of the form.

Pins n n and n n', inserted in the pin-holes e c of thecross locking-bars, hold the duplex locking-bars against the sides of the 'page or pages. Single wedges w w are inserted in the spaces d d, between the duplex locking bars and between one of the cross locking-bars and pins m m', as shown in Fig. 1, for forcing the cross locking-bars against the ends of the page to hold it securely clamped endwise. Duplex wedges w w', straddling the cross lool;- ing-bars D D and working between the dupleX locking-bars C and pins n u', force said duplex locking-hars against the sides of the type to be locked up, as shown7 and rmly clamp the page sidewise.

The manner in which the several devices employed in my invention operate is as follows: When it is desired to look up a form in the chase the operator will place the chase on the imposing stone, and then proceed to place within the same the locking-bars.

is done by first inserting the cross lockingbars D in the spaces d d, formed between the bars composing the duplex locking-bars C C, when said bars thus connected lare set within rIhis IOO the chase. The supporting-bars B B are then inserted in place by passing them through the perforations a a in one ofthe sides A A of the chase and through the spaces d d between the duplex lockingbars, and thence through the perforations a a ot' the opposite side piece A ot' the chase, when the said locking-bars C C will be held within the chase, with their ends bearing against the inner side surfaces ot' the sides A A and ends A A, to prevent shifting endwise in either direction. The operator will then proceed to form a square corner, against which the page is to be set bet'ore locking up. This is done by inserting pins a a into some one of the several pin-holes e ein each cross locking-har, so that the pins will be in range with each other, and also by inserting pins m m in pin-holes c c of the locking-bars C C, also in range with each other, so that lines drawn through pins n u and m m will be at right angles with each other. The operator will then move one ot' the bars C against pins n a and the other bar C off at a distance therefrom. He will then move 011e ot" the bars D against the pills m m and the other bar D oft' at a distance therefrom, when the bar l), bearing against pins m m, will be at right angles with the bar C, bearing against pins n n, and the square corner will be formed. The operator will then place the page in the square corner formed as above described, when the other bar C (right -hand side) will be moved up against the right-hand side of the page, and the other barI) (top bar) will be moved down to bear against the top of the page. Pins m m and n' fn are then to be inserted in pinholes near the outer edges of bars C and D, and wedges lw tu and fw w are crowded between the respective bars and pins they operale with, when the form will be securely locked up. The operator will then tighten the clamping-screws s s in bars C C, so as to cause them to tightly clamp said supporting-bars, when the locking-up device will be securely held in place within the chase. When it is desired to remove the locked-up page from the chase the operator will be required only to withdraw the supporting-bars B B after the clampingscrews s s have been loosened.

The page or matter may be locked up at one corner ot' the chase, as 'shown at F in Fig. 4, or may be locked up diagonally, as shown by full lines in Fig. 5, while pages or matter set diamond-shaped,or with oblique ends or sides, as shown by dotted lines in Fig. 5, may also be readily looked up.

In locking up forms of several pages for book-work three or more duplex locking-bars, together with three or more cross locking-bars, are to be employed, and with a corresponding number of pins and wedges. In such a case all reglets are dispensed with and the divisions between the forms will be made by the locking-bars themselves, as shown in Fig. (i.

Among the advantageous results obtained by the employment of my invention are these:

No strain or pressure is brought against the end and side portions of the outer frame, A A, as it will be readily observed that the lockingbars and their pins receive all the pressure incidental to the locking-up ot" type; that all necessity for employing furniture, such as head, foot, and side sticks, reglets, and large quoins, is fully obviated.

The pages or matter will be clamped at points or on horizont-al lines between their base or foot edges and their face edges, and, being steel, the locking-bars will not yield before pressure, as does the wood furniture heretofore employed. Forlocking up pages other than rectangular, and when type or matter is set in the forms of rhombuses or rhomboids, all 'use ot special furniture will be dispensed with.

` Forms may be locked up in galleys for proving by using two or more duplex locking-bars (according to the number of galleys to be proved) and moving the cross locking-bars toward the ends of the chase and lixing the locking-bars by pins and wedges. A number ofjobs may be locked together in one locking device and set aside, While the outer frame may be employed to hold other matter. AbsoluteA squareness ot' corner can he readily obtained and preserved for properly inserting a rectangular page,while the proper angle of corner for diagonal pages may be readily made. The mitered rules bounding the sides and ends of a form will be securely held from shifting endwise. AThe employment of gutters is dispensed with in book-forms, whether composed ot' two, four, or more pages. In large jobs, such as show bills or cards, the cross lockingbars are made to operate to support the center ot' the large forms, and all necessity of employing reglets is obviated. The locking-bars may be'employed as a substitute for tyingcords, and be used to hold pages together when removed from the outer frame and laid away.

Having described my invent-ion, what I claim, and desire to secure by Letters Patent, 1s-
